VIDEO-'Do The Math' Documentary Premieres on Earth Night April 21 | Occupy America

The "Do the Math" Movie is being screened at house-parties and screenings across the country on April 21st. At 42 minutes, it tells the story of the rising movement to change the terrifying math of the climate crisis and fight the fossil fuel industry.

Two panel discussions featuring Bill McKibben, Dr. James Hansen, and movement allies and leaders will be live-streamed at 8 p.m. ET and then at 8 p.m. PT.

The documentary follows founder Bill McKibben on last November's Do the Math tour that reached over 25,000 people at sold-out shows in 21 cities across the country (and tens of thousands more online). Part TEDTalk, part revival meeting, the Do the Math show built off of an article called "Global Warming's Terrifying New Math" that Bill had published in Rolling Stone earlier in the summer. The piece became one of the most viral stories ever published by the magazine, garnering over 125,000 likes on Facebook and millions of page views.

In the article, and onstage throughout the tour, Bill laid out three numbers that explain our current crisis: In order to limit global warming to below 2 degrees Celsius, scientists say we can emit only 565 more gigatons of carbon dioxide into the atmosphere, but the fossil fuel industry has roughly 2,795 gigatons of carbon dioxide just in their reserves, over five times too much. In other words, the fossil fuel industry is a rogue industry, outlaws not against the laws of the United States -- for the most part they get to write those laws but against the laws of physics and chemistry.
